Teaching Design And Implementation Of Ionization Equilibrium Based On 5E Learning Ring

In high school chemistry courses,ionization equilibrium is the upper bearing of electrolyte solution and chemical equilibrium,and the lower bearing of salt hydrolysis and precipitation solution equilibrium.It plays a pivotal role in chemistry learning and is also the key and difficult point in high school chemistry teaching.At present,the new chemistry curriculum in China focuses on the development of the core quality of the chemistry discipline,and advocates the development of a variety of exploration activities based on chemical experiments in the teaching activities,so as to promote the change of students' learning methods.Therefore,how to better promote the teaching of ionization balance under the concept of the new curriculum is a problem that every educator should think about.5E learning loop is based on the theory of piaget's epistemology,emPHasizes the students in a cognitive conflict problem situation,independent inquiry activities,experiences of new knowledge and old knowledge never balance to balance the construction process,achieve scientific concept,and then the essence of which is to explore the core,and can promote knowledge of meaningful learning a kind of teaching mode.In this study,5E learning ring was selected as the theoretical guidance to conduct effective teaching research on ionization balance,in order to provide some references for the teaching of ionization balance.Were reviewed in this study of ionization balance for teaching research and 5E ring,on the basis of application research in chemistry teaching in 5E learning ring for theoretical guidance,first determine the teaching scheme based on 5E learning ring design general train of thought and ionization balance the feasibility and necessity of using 5E learning ring,and then analyzes the teaching content,students' learning,and application of 5E learning teaching strategies,formed a study based on the 5E ring ionization balance of teaching design and teaching practice.Finally,the practical results are tested and discussed.The practice results show that the teaching design scheme based on 5E learning ring is helpful to promote the teaching effect of ionization balance.The innovation of this paper lies in that under the guidance of the theory of 5E learning ring,the general idea of designing teaching scheme based on 5E learning ring is formed.The teaching design of 5E learning loop for ionization balance is developed,and the effective teaching effect is obtained in the teaching practice.
